I've just created a a dvd in DVDA and when I watch it through a media player (Kplayer, VLC, Nero showtime) the menu lose a lot of quality about 5 seconds in. You know in a program when you can choose between high or medium quality and you can instantly see the differences if you toggle between these options, well that's pretty much what it looks like.

I created the background of the menu in After effects and it is a 15 second sequence where nothing moves.

I have two chapters and I animate them for 10 seconds then loop. These two don't lose quality though. It is only the background.

I have experienced this with DVDA 2 and 3 every now and then. Actually 2 times since early version 2. You probably aren't doing anything wrong it seems to be just something that happens once in a while. I have never found a plausible explaination or fix OTHER than re-rendering the project. On the 2 iccassions I have done this the problem was solved.
I know it a PITA but I know of no good reason for this to happen nor do I know of any other way to fix it.
Good luck,
Don

PREFACE: I am not a stranger to the software, so I think it is something else. I have not made any "simple" or basic mistakes...I hope.

I am using Sony DVD Architect to make a widescreen 24p ntsc DVD out of a Sony Vegas project. The problem is, when I play the DVD, it is slightly vertically stretched. Not a lot, just a bit. I have played it on a widescreen computer, widescreen TV through a DVD player, and widescreen TV through an Xbox 360. Each time, when played at "native" rez and aspect, it is slightly vertically stretched. I can FORCE it to fit and then it's fine, but at native settinjgs, it is never right.

1) I made sure all the clips are 720 x 480.
2) I made sure the project setting is 720 x 480.
3) I rendered out using the DVD Architect presets for DVDA Widescreen 24p mpg-2.
4) I made sure the DVD Architect project matched the 720 x 480 settings.
5) I render....
6) Native aspect is never right. It is never actually 720 x 480. Or maybe it IS 720 x 480 and my TV or computer monitor is not. I don't know.

I don't know, but it's killing me. I need to master this DVD very soon.

P.S. I have made DVDs before this way and have not had a problem until now.
